CAPT OF A WDB CARGO TURNED OFF RWY AFTER LNDG ON A CLOSED HIGH SPD TXWY. SUBSEQUENTLY PWRED BACK TO CLR BLOCKED AREA TO CONTINUE TAXI TO THE RAMP. TXWY WAS NOTAMED CLOSED PER COMMERCIAL ARPT DIAGRAM INFO. CAPT COMPLAINS OF BEING OVERWHELMED WITH SO MANY ARPT NOTED CHANGES AND CLOSURES TO REMEMBER QUICKLY AT THE RIGHT TIME.

Narrative

RPT IS MADE NOT AS THE RESULT OF AN INCIDENT WHICH CAUSED MUCH OF A PROB; BUT AS ONE WHICH HOPEFULLY WILL ADD TO THE HUMAN FACTORS DATABASE CONCERNING THE VOLUME OF INFO WHICH SOMETIMES OVERLOADS A PLT. OUR COMPANY COMMERCIAL MANUAL CONTAINS 9 TEMPORARY PAGES CONCERNING APCH CHANGES; PARTIAL TXWY CLOSURES; CONSTRUCTION; ETC -- ALL OF WHICH ARE IN EFFECT AT VARYING TIMES; DATES; EVEN MONTHS. ALL OF WHICH IS SOMETIMES DIFFICULT TO RETAIN IN ITS ENTIRETY AND AS I FOUND SOMETIMES DIFFICULT TO RECALL IMMEDIATELY EVEN AFTER STUDY. RWY AND APCH CHANGE OSAKA KIX. LOW VISIBILITY; WET RWY; TXWYS. LANDED; ROLLED OUT AND STARTED TO TAKE THE HIGH SPD TURNOFF WHICH WAS NOT APPROPRIATE FOR SPD AND RAMP PARKING LOCATION. HIGH SPD TURNOFF LIGHTS WERE ILLUMINATED. AS I STARTED TO TURN OFF; I NOTICED POORLY LIT HWY CONES INDICATING HIGH SPD WAS CLOSED 100+ YARDS AHEAD WITH NO EXIT FROM HIGH SPD. ACFT WAS STOPPED; NOSE JUST INTO THE TURNOFF; WITH TAIL STICKING WELL ONTO RWY. I WAS CONCERNED THAT I MIGHT HIT A TXWY LIGHT APPROX 1 FT HIGH AND I MADE A L TURN BACK TO THE RWY; R TURN NOT POSSIBLE. ALSO NOT HAPPY ABOUT BEING STUCK WITH TAIL ON AN ACTIVE AND THE ONLY RWY. ASKED TWR TO PULL AHEAD AND GET A TUG. THEIR RESPONSE BASICALLY 'STANDBY OR BACK UP' AND GO DOWN RWY. WHILE WE DON'T NORMALLY PWR BACK IN THIS ACFT LITTLE ABOVE REVERSE IDLE ALLOWED ME TO ROLL BACK THE THEN 10 FT NEEDED TO CLR THE LIGHT AND TAXI TO THE RAMP. NOTAMS HAD BEEN CHKED; COMMERCIAL CHART PAGES REFERENCED; ATIS DID NOT HAVE TXWY CLOSED; TWR DID NOT OFFER ANY DIRECTION AFTER LNDG; TXWY LIGHTS WERE ON. I TRIED TO TAKE IT AND WAS INCORRECT. FURTHER RESEARCH ON MY PART AS TO WHAT ILLUMINATED TXWY LIGHTS MEAN IS ONGOING.
